I don't know the particulars of Oklahoma, but here is some general advice:

In general, tax parcels are the responsibility of each County. One way to potentially get them would be to contact each County's Assessor's Office. However, some counties may not have it available in GIS format, or even in downloadable format. There also may be a cost associated with acquiring the data.

Another option for parcels may be to do a search on commercial companies that sell the records. This may cost quite a bit of money, but in some cases be the only way one can get the data. For example, some counties in Nevada have decided to have a single commercial company handle all parcel data for them; maybe some counties in Oklahoma do the same?

State Agencies can sometimes be a good source of data for Topography and Well Production. You may have to do a bit of digging; however, as the Agency that handles a particular topic is not always be what would seem to be the obvious one. As an example of a totally not obvious one from neighboring Texas, petroleum is handled by the Texas Railroad Commission.

"What does the Railroad Commission have jurisdiction over?

The Railroad Commission of Texas (Commission) is the state agency with primary regulatory jurisdiction over the oil and natural gas industry...."

Another option for Topography and Well Production is Federal Agencies. At that level, I'd start with the US Geological Survey (USGS). There are several other agencies who may also have the data; it will take a bit of searching.
